ENGINE-HOOD SHUTTER.

Application filed February 24, 1920. Serial No. 860,810.

To all whom itmay concern:

Be it known that I, GEORGE F. LELANSKY, a citizen of the United States, residing at Canton, in the county of Stark and State of Ohio, have invented certain new and useful Improvements in Engine-Hood Shutters, of which the followin is a specification.

The invention re ates to shutters in the hoods of internal combustion engines for controlling the current of cooling air entering the hood; and the object of the improvement is to provide a shutter of simple construction and operating connections, having a spring pressure control for each individual vane, to prevent a rattling of the same, and a further object is to provide spring controlled operating connections extending from the shutter to the hinged end of the hood, with abutting means on the dash Wall of the machine for conveniently controlling the operation of the shutter.

These objects are attained in a general wa by providing a pivotal support for eac vane, and an operating bar traversing one side of the vanes, with a J-shaped spring connecting the bar with each vane; and by providing a bell crank for operating the reciprocating bar, a spring control rod leading from the bell crank to the hinged end of th hood, and a ratchet bar in the dash hood impinging the end of the push bar.

A practical embodiment of the invention, applied to a hood hinged to the top of the dash, is illustrated in detail in the accompanying drawings, in which- Figure "1 is an inside elevatlon of the improved shutter;

Fig. 2, a section on line 2-2, Fig. 1;

Fig. 3, a fragmentary enlarged section showing two vanes in open position;

Fig. 4, a similar section showing the vanes in closed position;

Fig. 5, a detached view of one vane spring; and Y/ 1 Fig. 6, a fragmentary perspective view of a portion of the shutter, showing one vane detached from its pivotal support.

Similar numerals refer to similar parts throughout the drawings.

The hood 1 of an internal combustion engine of the air cooled type is provided with an opening 2 in its forward end, in the rim of which opening is mounted the frame 3 of theshutter.

Bearing plates 4, preferably made of sheet metal, are secured to the sides of the frame, and have a series of tongue flanges 5 cut at intervals along their inner ed es, which flanges are bent first inward to an mclination upward and thence downward at an acute angle, L-shape, to form V-shaped pivotal bearings 6 for the shutter.

The vanes 7 are also preferably made of sheet metal, and are bent downward to form obtuse angle flanges 8 along each side. edge to stiffen the vanes longitudinally, one of which flanges forms a yielding abutment for impinging and fitting the face of the con-v adjacent to the inner free or swinging edges.

of the vanes and may be positioned at one sid of the median line of the shutter, as shown in Fig. 1; and is pivotally connected at its lower forwardly curved end 12 to the rear end of the link 13 and at its up er forwardly curved end 14 to the rearwardly disposed an le 15 of the bell crank 16, the forward en s of the link and the L-arm of the bell crank being pivotall connected with the lower and upper mem ers respectively of the shutter frame 3.

The free or swinging side of each vane is individually connected to the shutter bar 11 by a J-shaped spring 17, the curved end 18 of each spring being fixed to the shutter bar as by two'rivet pins 19, and the stem end thereof being pivoted to the adjacent flange 8 of the vane, as by engagement of the hook 20 on the spring in the aperture 21 in the vane.

The normal shape of the vane springs is shown in Fig. 5, and the parts of the shutter are so proportioned and arranged that the s ring is partially distorted or deflected w en the vanes are full open as shown in Figs. 2 and 3, and are distorted or deflected to a much greater extent when the vanes are entirely closed as shown in Fig. 4; and the energy or tension of the springs serves the double purpose of holding the fulcrum edges of t e vanes rearwardly in their V-shaped'pivota1 bearings at all times, and of acting to swing the operating bar and the connected edges of the vanes, downward and rearward from the closed position shown in Fig 4, to the open position shown in Figs.

,2 and 3.

The vanes may be stopped in completely closed gmsition by the abutment of the upper face 0 one vane against the edge flange of another vane, as shown at 22 in Fig. 4; and

the vanes may be stopped in full open .position, when the forward edge portions of their facesbear against the under sides of the heavy flanges,as shown at 23 in Fig. 3; by the abutment of the lug 24 in the bell crank with the'frame of the shutter; and it is evident that the action of the individual springs serves to firmly hold all these parts in contact and revents a rattling of any one part upon anot er.

The control rod 25 is longitudinally located in the top of the hood, and is supported for endwise sliding movement at its rear end in the upright guide flange 26 on the forward end of the bracket 27 having its rear end secured to the rear frame 28 of the hood. The forward end of the control rod is provided with the adjustable yoke 25' which is pivotally connected with the upright arm or stem of the bell crank 16; and upon its rear end is secured the mushroom head 29, between which head and the guide flange 26 is located the compression spring 30, which is coiled around the rear end of the control rod.

The compression spring 30 acts to move the control rod rearward, and through the bell crank 16, to swing the shutter bar rearward and downward; and the energy of this spring supplements the weight of the vanes and the shutter bar, and the combined action of the individual vane springs, to normally hold the shutter vanes in open position, as shown in Figs. 2 and 3; and it is evident that the shutter vanes may be partially or entirely closed by merely pushing the control bar forward far enough "to effect the desired closure.

The ratchet bar 31 longitudinally is located in the top of the dash hood of the machine, in alignment with the control rod, and is mounted for endwise sliding movement at its forward end in the slotted guide plate 32 secured to the dash wall 33, and at its rear end in the slotted escutcheon secured to the instrument board 34 of the machine. The lower edge of the rear portion of the ratchet bar is provided with a series of notches 35 arranged to engage the lower end" of the es ut he n slot for locking the bar in various positions, and 'its rear end is provided with a suitable knob or handle 36, for conveniently moving it to and fro. A cotter pin 37 or the like may be used in its forward end to prevent a withdrawal of the bar from the forward guide plate, and a spring 38 may be provided to hold the ratchet bar in engagement with the escutcheon. 4

Suitable apertures 39 and 40' are provided in the rear frame 28 of the hood and the contiguous dash wall 33 of the machine, for accommodating the mushroom head 29 onthe rear end of the control rod and the protruding forward end of the ratchet bar; and the hood may be connected at the top to the dash by a hinge 41 in well known manner.

'The parts are preferably so arranged that when the shutter vanes are wide open and the control bar held by the compression spring in its rearmost position, the mushroom head on its rear end will be in contact with the forward end of the ratchet bar when the same is engaged by the escutcheon at or near its rearmost position; it being understood that the engine hood is in its normal closed position. with its rear fi re against the dash wall of the machine, a l as shown in Fig. 2. In this position of the parts, it is evident that the hood can be opened and closed without in any manner affecting the condition of the shutter or the position of the control rod and ratchet bar, which remain in proper position for action whenever the hood is closed.

When, however, it is desired to close the shutter vanes, either partly or entirely, the same is done by disenga g the rear end of the ratchet bar from t e escutcheon and then pushing the ratchet bar and with it the control rod forward, thereby rotating the bell crank and swinging the shutter bar upward and forward, until the shutter vanes are closed to the desired extent, whereupon one of the rack bar notches is engaged with the escutcheon, which looks the bar and holds the control rod against the action of the compression spring, and the shutter bar against the action of the individual vane spring in the proper position for maintaining the shutter vanes in the desired position, whether it be only partly or entirely closed. In this position of the parts, it is evidentthat if the engine hood be opened the compression spring will act to open theshutter, but that when the hood is again closed, the protruding forward end of the ratchet bar will impinge the mushroom head on the rear end of the control bar, and close the shutter as it was before.

And finally, to reopen the shutter it is only necessary to disengage and pull the ratchet bar back into normal position, whereupon the compression spring, as well as the individual vane tension springs, automatically act to swing the vanes wide open and to maintain them in such position.

I claim:

1. A shutter including a support, vanes having V-shaped pivotal bearings in the support, and a separate spring associated with each vane acting to hold it in its pivotal bearing.

2. A shutter including a support, vanes fulcrumed on the support, a bar operatively connected with the support, and J-shaped springs fixed at their curved ends to the bar and connected at their stem ends with the several vanes.

3. A shutter including a support, vanes having V-shuped pivotal bearings on the support, a bar operatively connected with the support, operating connections between each vane and the bar, and tongues on the vanes acting on the bearings for retaining the vanes therein.

4. A shutter including a support, vanes fulcrumed on the support, a bar operatively connected with the support, operating spring connections between each vane and the bar, and a spring actuated control rod normally holding the shutter vanes open.

5. A shutter including a support, vanes fulcrumed on the support, a bar operatively connected with the frame, operating connections between each vane and the bar, a spring actuated control rod normally holding the shutter "anes open and means for impinging the end of the control rod to hold the shutter vanes in various positions of closure.
